Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a scraping-synchronous cleaner. Background Technology

[0002] Commercially available cleaning devices are mainly divided into two types: wiping cleaners and scraper cleaners. Wiping cleaners rely on a wet wiping surface to remove dirt, but often leave water residue after wiping. Scraper cleaners have a scraper at the end to remove dirt and liquid together. However, they usually require pre-wetting the surface, adding an extra step to the cleaning process. Furthermore, these traditional tools are mostly simple in structure and lack a coordinated design, failing to complete the two key cleaning steps of wiping and scraping in a single motion.

[0003] Some glass cleaners with composite structures integrate the wiping body and the scraper, enabling simultaneous wiping and squeegee operations. For example, the Chinese utility model patent CN202891790U describes a multi-purpose glass cleaner. While its wiping surface and scraper are designed to be on the same side, allowing simultaneous contact with the glass, the fixed position and angle of both necessitate a specific posture for the user. When cleaning glass at heights, the user must continuously raise their arm and maintain a fixed angle, which can easily lead to hand muscle fatigue over time and even incomplete cleaning due to stiffness. Furthermore, the single wiping surface of the wiping body limits the effective usage time of the glass cleaner—when the wiping surface becomes dirty, the cleaning process must be interrupted for cleaning. For cleaning large areas of glass, frequent handling increases the overall time required. Utility Model Content

[0004] The purpose of this invention is to provide a simultaneous wiping and scraping cleaner that can complete wiping and scraping in a coordinated manner. It is flexible and efficient to use, avoids hand fatigue, and reduces the number of cleaning interruptions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scraping-synchronous cleaner includes a T-shaped frame, a scraper at one end of the T-shaped frame, and a cleaning component disposed below the scraper. A support frame is provided on the T-shaped frame, and a first support rod and a second support rod are retractably provided on the support frame. The two ends of the cleaning component are respectively mounted on the first support rod and the second support rod. When a scraping operation is performed on the surface to be cleaned and the scraper is in close contact with the surface to be cleaned, a contact force is generated between the working surface of the cleaning component and the surface to be cleaned. The first support rod and the second support rod extend and retract so that the working surface of the cleaning component is always in contact with the surface to be cleaned. When the working surface of the cleaning component leaves the surface to be cleaned, the first support rod and the second support rod return to their original positions.

[0007] Preferably, the support frame includes a first connecting rod and a second connecting rod fixedly connected to the T-shaped frame. The first connecting rod is parallel to the first support rod, and the second connecting rod is parallel to the second support rod. A first connecting part is provided between the first support rod and the first connecting rod. A second connecting part is provided between the second support rod and the second connecting rod.

[0008] Preferably, the first connecting part includes a first rotating plate and a first fixed plate. The two ends of the first rotating plate are rotatably connected to the first support rod and the first connecting rod respectively by pins. One end of the first fixed plate is welded to the first connecting rod, and the other end is provided with a first through hole for the first support rod to pass through. A first return spring and a first limiting part are sleeved on the first support rod, and the two ends of the first return spring are in contact with the end faces of the first limiting part and the first through hole respectively. The second connecting part includes a second rotating plate and a second fixed plate. The two ends of the second rotating plate are rotatably connected to the second support rod and the second connecting rod respectively by pins. One end of the second fixed plate is welded to the second connecting rod, and the other end is provided with a second through hole for the second support rod to pass through. A second return spring and a second limiting part are sleeved on the second support rod, and the two ends of the second return spring are in contact with the end faces of the second limiting part and the second through hole respectively. When the cleaner is not subjected to external force, both the first return spring and the second return spring are in their natural state.

[0009] Preferably, both the first support rod and the second support rod are provided with a plug at the end away from the cleaning component; the first through hole and the second through hole are both strip holes, which are arranged in the vertical direction so that the first support rod and the second support rod can move in the strip holes when the first return spring and the second return spring are compressed.

[0010] Preferably, the first support rod is a first spring damper, the second support rod is a second spring damper, and the damping rod ends of the first and second spring dampers are connected to both sides of the cleaning component; the first connecting part includes a third rotating plate and a third fixed plate, the two ends of the third rotating plate are respectively rotatably connected to the damping rod of the first spring damper and the first connecting rod by pins, one end of the third fixed plate is welded to the first connecting rod, and the other end is rotatably connected to the fixed seat of the first spring damper; the second connecting part includes a fourth rotating plate and a fourth fixed plate, the two ends of the fourth rotating plate are respectively rotatably connected to the damping rod of the second spring damper and the second connecting rod by pins, one end of the fourth fixed plate is welded to the second connecting rod, and the other end is rotatably connected to the fixed seat of the second spring damper.

[0011] Preferably, the T-shaped frame is bent toward the cleaning component to form an arc-shaped transition surface, so that when the cleaning component is in use, the side of the scraper closest to the surface to be cleaned forms an acute angle with the surface to be cleaned during the movement of the scraper.

[0012] Preferably, the cleaning component includes an intermediate shaft and a bushing sleeved around the intermediate shaft. A damping mechanism is provided between the intermediate shaft and the bushing sleeve. The damping generates friction between the intermediate shaft and the bushing sleeve to slow down the rotation speed of the bushing sleeve, thereby allowing the bushing sleeve to rotate and change surfaces when the working surface of the cleaning component gets dirty during operation; or the bushing sleeve has a polygonal cross-section.

[0013] Preferably, the cleaning component includes an intermediate shaft and a bushing sleeved around the intermediate shaft, with both ends of the intermediate shaft extending beyond the bushing to form extension sections; a U-shaped fork is provided at one end of the first support rod and the second support rod that connects to the cleaning component, a first locking part is provided on the extension section, and a second locking part is provided on each of the two side walls of the U-shaped fork, and the extension section is respectively inserted into the U-shaped fork on the corresponding side so that the first locking part and the second locking part are locked together.

[0014] Preferably, the cleaning component is a flat plate with a wiping agent. Protrusions are integrally formed at both ends of the flat plate. A U-shaped fork is provided at one end of the first support rod and the second support rod that connects to the cleaning component. A first locking part is provided on the protrusion, and a second locking part is provided on each of the two side walls of the U-shaped fork. The protrusions are respectively inserted into the U-shaped fork on the corresponding side, so that the first locking part and the second locking part are locked together.

[0015] Preferably, the length of the scraper is not less than the length of the cleaning component; the T-shaped frame includes a crossbar and a vertical bar fixed in the middle of the crossbar, an extension bar is connected to the end of the vertical bar away from the crossbar, and a handle is provided at the other end of the extension bar.

[0016] In the above technical solution, the wiping and scraping functions are executed simultaneously by setting the scraper and cleaning component vertically. The cleaning component first contacts the surface to be cleaned, wetting and wiping it. Then, the scraper immediately scrapes away the wiped area, pushing liquid and residual stains away from the surface, achieving quick drying. This phased and simultaneous cleaning sequence avoids the tedious steps of traditional cleaners, such as repeatedly wiping to remove water stains and pre-wetting the surface. The operator only needs a single push-pull motion to complete the entire cleaning process, saving time and effort.

[0017] By setting the end of the cleaning component flush with the end of the scraper, and by using spring dampers for both the first support rod and the second support, the scraper can always remain in close contact with the surface to be cleaned, regardless of the angle at which the user cleans the surface, unaffected by the cleaning component. During the cleaning process, the spring damper is compressed by the reaction force of the surface to be cleaned, providing elastic buffering for the cleaning component and reducing damage to both the cleaning component and the surface to be cleaned from instantaneous forces. When the user changes the cleaning angle, and the magnitude and direction of the force applied to the cleaning component by the surface to be cleaned changes, the spring damper can dynamically adjust the support force on the cleaning component through extension and contraction. When the pressure increases, it compresses and stores energy, using elastic restoring force to balance the pressure, preventing the cleaning component from damaging the surface to be cleaned or deforming itself. When the pressure decreases, it releases energy, pushing the damping rod to extend, allowing the cleaning component to fit tightly against the surface to be cleaned. This ensures that while the scraper and the surface to be cleaned are in stable contact, the cleaning component can also maintain stable contact with the surface to be cleaned, maintaining efficient cleaning.

[0018] Rotary plates are installed between the first connecting rod and the first support rod, and between the second connecting rod and the second support rod, respectively, to achieve a rotatable connection between the support rod and the support frame, facilitating the back-and-forth movement of the cleaning component. Return springs are fitted onto the two support rods, and the springs are limited by the openings in the fixed plates and the limiting parts on the support rods. When the cleaner scrapes, the reaction force from the surface to be cleaned causes the support rod to retract along the through-hole, and the compression of the return spring provides elastic buffering, reducing instantaneous force damage. When the cleaning angle changes, causing a change in the force on the cleaning component, the return spring dynamically adjusts the support force through extension and contraction. Increased pressure stores energy to balance the pressure and prevent damage; decreased pressure releases energy to push the support rod out, thus ensuring stable contact between the scraper and the surface to be cleaned, while also maintaining stable contact between the cleaning component and the surface to be cleaned, maintaining efficient cleaning.

[0019] By setting the T-shaped frame to bend towards the cleaning surface, the side of the scraper closest to the surface being cleaned will always be in acute-angle contact with the surface during the scraping process. This ensures effective scraping and makes force transmission more efficient, reducing wasted effort. Moreover, unlike some traditional tools, it eliminates the need to continuously raise the arm and maintain a fixed angle when cleaning high surfaces, avoiding hand muscle fatigue and making the cleaning process more comfortable.

[0020] By adding silicone oil between the circular cross-section cleaning component and the mounting bracket, a damping effect is increased. This controls the replacement speed of the cleaning surface of the cleaning component, allowing the cleaning component to make fuller use of the cleaning capacity of each cleaning surface and extending the overall effective cleaning time. It also prevents the cleaning component from shaking excessively and maintains the stability of the cleaning process.

[0021] By setting the cross-section of the cleaning component to be triangular or rectangular, the replacement speed of the cleaning component can also be controlled, and the edges can concentrate the force, generating greater pressure on the stains, further improving the ability to remove stubborn stains, and allowing the surface to be cleaned to be cleaned more thoroughly.

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings:

[0037] like Figures 1 to 13As shown, this simultaneous scraping cleaner includes a T-shaped frame 10, which includes a horizontal bar 11 and a vertical bar 12 connected to the horizontal bar 11. The vertical bar 12 is connected to the middle of the horizontal bar 11 and is integrally formed with the horizontal bar 11. A scraper 13 is fixed to the end of the T-shaped frame 10. The scraper 13 is made of silicone and its edges are designed in a wedge shape to enhance the scraping effect. A cleaning element 14 is provided below the scraper 13. The length of the scraper 13 is not less than the length of the cleaning element 14, so that the scraper 13 can completely cover the area wiped by the cleaning element 14 during the scraping process, avoiding the failure to remove water stains at the edges due to the difference in length between the two. The cleaning element 14 can be a common flat plate 145 with a wiping material 147, which is used to clean the surface to be wiped. The cleaning component 14 can also have other structures. Preferably, the cleaning component 14 includes an intermediate shaft 141 and a bushing 144 sleeved around the intermediate shaft 141. The bushing 144 is a cleaning sponge or cleaning cotton, used to wet and wipe away stains on the surface to be cleaned. The front side of the cleaning component 14 is flush with the front side of the scraper 13. A support frame 20 is provided on the T-shaped frame 10. The support frame 20 is telescopically provided with a first support rod 232 and a second support rod 233. The two ends of the cleaning component 14 are respectively installed on the first support rod 232 and the second support rod 233, so that the cleaning component 14 is telescopic. This allows the cleaning component 14 to always maintain close contact with the surface to be cleaned, whether the surface is high or low, while the scraper 13 is in contact with and able to scrape away water stains on the surface to be cleaned. This enables the wiping and scraping operations to be performed simultaneously, thus cleaning the surface to be cleaned in one action and improving labor efficiency.

[0038] When the cleaning component 14 is a flat plate 145 structure with a wiping material 147, protrusions 146 are integrally formed at both ends of the flat plate 145; when the cleaning component 14 is a structure in which a bushing 144 is fitted over an intermediate shaft 141, the two ends of the intermediate shaft 141 of the cleaning component 14 extend beyond the bushing 144 to form extension sections 142. A U-shaped fork 230 is provided at the end of the first support rod 232 and the second support rod 233 that connects to the cleaning component 14. The U-shaped fork 230 cooperates with the protrusions 146 or the extension sections 142, and a first locking part is provided on the protrusions 146 or the extension sections 142. A second locking part is provided on the two side walls of the U-shaped fork 230. The protrusions 146 or the extension sections 142 are respectively inserted into the U-shaped fork 230 on the corresponding side and the first locking part and the second locking part are locked together to realize the detachable connection between the cleaning component 14 and the support frame 20. Furthermore, the first engaging part can be a positioning groove 143 or a positioning protrusion disposed opposite to each other on the outer wall of the protrusion 146 or the extension 142, and the second engaging part can be a U-shaped fork protrusion 231 that cooperates with the positioning groove 143 or a U-shaped fork groove that cooperates with the positioning protrusion. The connection between the cleaning component 14 and the support frame 20 is achieved by the deformation of the U-shaped fork 230.

[0039] The support frame 20 includes a first connecting rod 201 and a second connecting rod 202 fixedly connected to the T-shaped frame 10. The first connecting rod 201 is parallel to the first support rod 232, and the second connecting rod 202 is parallel to the second support rod 233. One end of the first connecting rod 201 is fixedly connected to one side of the crossbar 11 by bolts, and one end of the second connecting rod 202 is fixedly connected to the other side of the crossbar 11 by bolts. The first connecting rod 201 and the second connecting rod 202 are symmetrical about the vertical rod 12. A first connecting part is provided between the first support rod 232 and the first connecting rod 201, and a second connecting part is provided between the second support rod 233 and the second connecting rod 202. The first connecting part and the second connecting part are symmetrically arranged about the vertical rod 12.

[0040] In this embodiment, the first connecting part includes a first rotating plate 212 and a first fixing plate 211. One end of the first rotating plate 212 is rotatably connected to the outer wall of the first connecting rod 201 by a pin, and the other end of the first rotating plate 212 is rotatably connected to the outer wall of the first support rod 232 by a pin. The second connecting part includes a second rotating plate 216 and a second fixing plate 217. One end of the second rotating plate 216 is also rotatably connected to the outer wall of the second connecting rod 202 by a pin, and the other end of the second rotating plate 216 is rotatably connected to the outer wall of the second support rod 233 by a pin, thereby realizing the rotational connection between the first support rod 232 and the second support rod 233 and the support frame 20, so as to realize the back-and-forth movement of the cleaning component 14. A first return spring 213 is fitted onto the first support rod 232. One end of the first fixing piece 211 is welded to the first connecting rod 201, and the other end has a first through hole 214 for the first support rod 232 to pass through. A first limiting part 215 is also provided on the first support rod 232. The first return spring 213 is disposed between the first limiting part 215 and the first through hole 214, such that both ends of the first return spring 213 contact the end faces of the first limiting part 215 and the first through hole 214 respectively to limit the first return spring 213. A second return spring 213 is fitted onto the second support rod 233. Spring 218, one end of the second fixing piece 217 is welded to the second connecting rod 202, and the other end has a second through hole 219 for the second support rod 233 to pass through. The second support rod 233 is provided with a second limiting part 220. The second return spring 218 is disposed between the second limiting part 220 and the second through hole 219, so that the two ends of the second return spring 218 contact the end faces of the second limiting part 220 and the second through hole 219 respectively to limit the second return spring 218. When the cleaner is not subjected to external force, the first return spring 213 and the second return spring 218 are both in the natural state.

[0041] In this embodiment, a plug 221 is provided at the end of the first support rod 232 and the second support rod 233 away from the cleaning component 14. The plug 221 can be screwed or snapped onto the ends of the first support rod 232 and the second support rod 233 to prevent the first support rod 232 from coming out of the first through hole 214 and the second support rod 233 from coming out of the second through hole 219. The first through hole 214 and the second through hole 219 are both strip-shaped holes, which are arranged vertically so that the first support rod 232 and the second support rod 233 can move up and down in the strip-shaped holes when the first return spring 213 or the second return spring 218 is compressed. The vertical length of the strip-shaped holes limits the maximum moving distance of the first support rod 232 and the second support rod 233, so that the cleaning component 14 has sufficient elastic stroke to facilitate use by the customer at different angles.

[0042] During the scraping operation, the surface to be cleaned exerts a reaction force on the cleaning component 14. This reaction force is quickly transmitted to the first support rod 232 and the second support rod 233, causing them to retract along the first through hole 214 and the second through hole 219, respectively. At this time, the first return spring 213, sleeved on the first support rod 232, begins to compress under the thrust of the first fixing part, and the second return spring 218, sleeved on the second support rod 233, also begins to compress under the thrust of the second fixing part, providing elastic cushioning for the cleaning component 14 and reducing damage to the cleaning component 14 and the surface to be cleaned caused by instantaneous force. Even if the user changes the cleaning angle, and the magnitude and direction of the force exerted on the cleaning component 14 by the surface to be cleaned change, the return springs can still dynamically adjust the supporting force on the cleaning component 14 through extension and contraction. The return springs ensure that the cleaning component 14 also maintains stable contact with the surface to be cleaned while the scraper 13 is in stable contact with it, maintaining efficient cleaning.

[0043] In a preferred embodiment, the first support rod 232 is a first spring damper 222, and the damping rod end of the first spring damper 222 is connected to the left side of the cleaning component 14. The first connecting part includes a third rotating plate 224 and a third fixed plate 223. One end of the third rotating plate 224 is rotatably connected to the outer wall of the first connecting rod 201 by a pin, and the other end of the third rotating plate 224 is rotatably connected to the outer wall of the damping rod of the first spring damper 222 by a pin. When the damping rod extends or retracts, it provides a connection for the damping rod and prevents the damping rod from deforming after long-term use. The second support rod 233 is a second spring damper 226, and the damping rod end of the second spring damper 226 is connected to the right side of the cleaning component 14. The second connecting part includes a fourth rotating plate 228 and a fourth fixed plate 227. One end of the fourth rotating plate 228 is rotatably connected to the outer wall of the second connecting rod 202 by a pin, and the other end of the fourth rotating plate 228 is rotatably connected to the outer wall of the damping rod of the second spring damper 226 by a pin; thus realizing the rotational connection between the first spring damper 222 and the second spring damper 226 and the support frame 20, so as to realize the back-and-forth movement of the cleaning component 14. One end of the third fixing plate 223 is welded to the first connecting rod 201, and the other end is fixedly connected to the first convex shaft 2271. The first convex shaft 2271 is set perpendicular to the second spring damper 226. A first ring sleeve 2221 is fixedly connected to the end of the first spring damper 222. The first ring sleeve 2221 cooperates with the first convex shaft 2271 and is sleeved on the first convex shaft 2271 so that when the damping rod of the first spring damper 222 extends or retracts, the fixing seat of the first spring damper 222 can rotate with the first convex shaft 2271 under the drive of the third rotating plate 224. One end of the fourth fixing plate 227 is welded to the second connecting rod 202, and the other end is fixedly connected to the second convex shaft 2271. The second convex shaft 2271 is set perpendicular to the second spring damper 226. A second ring sleeve 2261 is fixedly connected to the end of the second spring damper 226. The second ring sleeve 2261 cooperates with the second convex shaft 2271 and is sleeved on the second convex shaft 2271 so that when the damping rod of the second spring damper 226 extends or retracts, the fixing seat of the second spring damper 226 can rotate with the second convex shaft 2261 under the drive of the fourth rotating plate 228. A blocking part 2232 is provided on both the first convex shaft 2231 and the second convex shaft 2271 to prevent the first ring sleeve 2221 from falling off the first convex shaft 2231 and the second ring sleeve 2261 from falling off the second convex shaft 2271. A first support beam 225 is fixedly connected between the third fixing plate 223 and the first connecting rod 201, and a second support beam 229 is fixedly connected between the fourth fixing plate 227 and the second connecting rod 202 to increase the stability of the support frame 20.

[0044] During the scraping operation, regardless of the angle at which the user cleans the surface, the spring damper ensures that the scraper 13 remains firmly in contact with the surface, unaffected by the cleaning component 14. Specifically, during cleaning, the scraper 13 is kept in constant contact with the surface. The cleaning component 14 experiences a reaction force from the surface, which is then transmitted to the damping rod. The damping rod compresses under pressure, providing elastic cushioning for the cleaning component 14 and reducing damage to both the cleaning component 14 and the surface. Even if the user changes the cleaning angle, altering the magnitude and direction of the force exerted on the cleaning component 14, the spring damper can still dynamically adjust its support force on the cleaning component 14 through extension, contraction, deformation, and rotation. When pressure increases, the spring damper further compresses and stores elastic potential energy, using elastic restoring force to balance the pressure and prevent the cleaning component 14 from damaging the surface or deforming itself. When pressure decreases, the spring damper releases elastic potential energy, pushing the damping rod out to ensure the cleaning component 14 remains tightly in contact with the surface, maintaining the cleaning effect.

[0045] In a preferred embodiment, the cleaning component 14 has a circular cross-section and is damped between the intermediate shaft 141 and the bushing 144, preferably with silicone oil, to increase the friction between the intermediate shaft 141 and the bushing 144. When the cleaning component 14 wipes the surface to be cleaned, the bushing 144 rotates more slowly along the axial direction of the intermediate shaft 141. For the cylindrical cleaning component 14, the rotation speed of the cleaning surface is effectively controlled during wiping, preventing the cleaning component 14 from frequently changing its cleaning surface due to rapid rotation. This ensures that the bushing 14 only rotates to change its cleaning surface after the working surface becomes dirty. This increases the friction between the cleaning component 14 and the surface to be cleaned, enhances the cleaning effect of the cleaning component 14, and extends the overall effective cleaning time of the cleaning component 14.

[0046] In a preferred embodiment, the cleaning component 14 has a polygonal cross-section, preferably triangular or rectangular. The triangle or rectangle is in face-to-face contact with the surface to be cleaned, increasing the friction between the surface and the cleaning component 14. During the cleaning process, without external interference, the automatic rotation of the bushing 144 along the intermediate axis 141 is suppressed. This prevents frequent switching of the cleaning surface, avoiding the need to manually switch to another surface after one side becomes dirty, thus extending the overall effective cleaning time of the cleaning component 14. Furthermore, the edges of the triangular or rectangular cleaning component 14 can concentrate the force, generating greater pressure on the stains, effectively wiping away stains adhering to the surface to be cleaned, and increasing the cleaning effect.

[0047] In a preferred embodiment, the end of the T-shaped frame 10 is bent towards the cleaning component 14 to form an arc-shaped transition surface. This ensures that when the cleaning component 14 is in use, the side of the scraper 13 closest to the surface to be cleaned forms an acute angle with the surface, guaranteeing both the scraping effect and making force transmission more efficient, reducing wasted effort. Furthermore, unlike some traditional tools, it eliminates the need to continuously raise the arm and maintain a fixed angle when cleaning high surfaces, preventing hand muscle fatigue and making the cleaning process more comfortable.

[0048] In a preferred embodiment, the end of the vertical bar 12 furthest from the horizontal bar 11 is threadedly connected to the handle 24, thereby increasing the gripping contact area and improving operational stability. An extension bar 241 is also provided between the vertical bar 12 and the handle 24. The extension bar 241 can be made of a metal tube and threadedly connected and fixed to the vertical bar 12 and the handle 24, which facilitates cleaning of high surfaces to be cleaned.

[0049] In a preferred embodiment, a connecting beam 203 is integrally formed between the first connecting rod 201 and the second connecting rod 202. The connecting beam 203 is perpendicular to both the first connecting rod 201 and the second connecting rod 202, so as to make the structure of the first connecting rod 201 and the second connecting rod 202 more stable and prevent bending or displacement when the first connecting rod 201 and the second connecting rod 202 are subjected to force. Furthermore, the connecting beam 203 is fixedly connected to the vertical rod 12 to increase the stability of the support frame 20.

[0050] When using this cleaner to clean the surface, first connect the extension rod 241 as needed, then wet the bushing 144. After wetting, there is no need to squeeze out the water; it can be used directly. Next, hold the handle 24 so that the cleaning component 14 first contacts and wipes the surface. The first support rod 232 and the second support rod 233, through elastic deformation, keep the cleaning component 14 in close contact with the surface, maintaining contact pressure whether cleaning a raised or lower surface. Then, the scraper 13 scrapes away the wetted area, using its wedge-shaped edge structure to push liquid and residual dirt away from the surface, leaving no watermarks and achieving quick drying. When the cleaning component 14 has a triangular or rectangular cross-section, manually change the side of the cleaning sponge or cotton as needed during cleaning. When all sides are quite dirty, remove the cleaning component 14 and replace it.

[0051] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the scope of protection.
